Descripción

General description

A cell-permeable pyrrolopyrimidine compound that acts as a potent, reversible, selective, and ATP-competitive inhibitor of Lck (IC₅₀ at 5 µM ATP = <1 nM, 2 nM, 70 nM, 1.57 µM and 1.98 µM for lck_64-509 Y³⁹⁴, Lckcd pY³⁹⁴, Src, Kdr and Tie-2, respectively; IC₅₀ at 1 mM ATP = 16 µM, 66 nM, 126 nM, 420 nM and 5.18 µM for Lck_64-509 Y³⁹⁴, Blk, Fyn, Lyn and Csk, respectively). Only minimally affects the activities of other kinases (IC₅₀ = 3.2 µM, >33 µM, >50 µM and >50 µM for EGFR, PKC, CDC2/B and ZAP-70, respectively). Also shown to potently block T-cell receptor-stimulated IL-2 production in vitro (IC₅₀<1-40 nM in Jurkat T cells) and in vivo (ED₅₀ = 4 mg/kg in mice, ip.)
